When QMux protocol is used, xprt_qmux layer is setup after SSL handshake completion but prior to the MUX initialization. Once transport parameters exchange is successful, the layer is removed and the MUX is started. The layer setup operation was performed directly on ssl_sock_io_cb(). Simplify the code by extracting it in a dedicated function xprt_add_l6hs(). The function is generic so the requested XPRT layer must be passed as argument. The code is mostly identical. One difference is that a check is performed to ensure no SSL handshake is pending. If this is the case, the function is a noop. This will become useful to support QMux transparently both in clear or on top of SSL. Another minor addition is that CO_FL_XPRT_READY flag is automatically resetted by xprt_add_l6hs(). This allows the code to use conn_xprt_start() standard function after XPRT init. |

HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
